Abstract—The applications of image processing for road
safety, detecting panels and roadway have attracted
considerable attention in literature and research, especially in
the field of information processing on embedded systems.
However, the demanding nature of image processing algorithms
conveys a substantial burden for any conventional real-time
implementation. Meanwhile, the emergence of reconfigurable
architectures, especially FPGA chips, which have been given
many facilities for rapid prototyping, where an image
processing algorithm, can be designed, tested, and synthesized
in a relatively short period of time compared to conventional or
traditional approaches. This paper studies a hardware and
software combination to obtain an optimal solution for the edge
detection, this step is considered essential for the detection of
panels and roadways, the dedicated algorithm is based on the
Laplacian calculation for Edges detecting and implemented in a
Xilinx Spartan 6 FPGA, and the results are displayed by
standing in a VGA monitor, with a sync and display controller.

Index Terms—Edge detection, Laplacian, real time, FPGA.
